Given numbers are 945, 138, 318, 430

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 138 are 2 x 3 x 23

Prime factors of 318 are 2 x 3 x 53

Prime factors of 430 are 2 x 5 x 43

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 945, 138, 318, 430

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(945, 138) = 43470

GCD(945, 138) = ( 945 x 138 ) / 43470

= 945 / 138

= 945

Step2:

LCM(3, 318) = 318

GCD(3, 318) = ( 3 x 318 ) / 318

= 3 / 318

= 3

Step3:

LCM(3, 430) = 1290

GCD(3, 430) = ( 3 x 430 ) / 1290

= 3 / 430

= 3

So, Greatest Common Divisor of 945, 138, 318, 430 is 1
